Among the more intelligent species of birds, genuine affection has been observed, strict monogamy and life-long unions having been established between mated pairs. Among others, although the conjugal bond is not life-lasting, so long as the mother-bird is caring for her brood, constancy to one another is the undeviating rule. We are assured that with the female Illinois parrot, “widowhood and death are synonymous,” and that “when a wheatear dies, his companion survives him scarcely a month.”[53]
All eagles are monogamous. Golden eagles live in couples and remain attached to one another for a hundred or more years, without even changing their domicile.[54] The conjugal unions of bald-headed eagles, although they are under no “legal restrictions,” last until the death of one of the partners. Among birds, although incubation rests with the mother, the father usually assists his companion. He not only takes her place if she desires to leave the nest for a moment, but also provides her with food.[55] So perfect is the bird family life that Brehm declares that “real genuine marriage can only be found among birds.”[56] Upon this subject we are informed that “examples of wandering fancy are for the most part rare among the birds, the majority of whom are monogamous, and even superior to most men in the matter of conjugal fidelity.”[57]
Concerning mammals, it is observed that although polygamy is frequent “it is far from being the conjugal regime universally adopted; monogamy is common, and is sometimes accompanied by so much devotion that it would serve as an example to human monogamists.”[58] Bears, weasels, whales, and many other animals choose their mates and go in pairs. Several kinds of monkeys are strictly monogamous.[59] Chimpanzees are sometimes polygamous and sometimes monogamous. It is stated what when a strong male has succeeded in driving away the other males of the group, the females, although in a position to subjugate him, are nevertheless kind and even tender toward him. They are doubtless too much occupied with their legitimate functions to rebel, but so soon as the young of the horde are grown, the usurper is driven from their midst. A little observation will show us that even among polygamous species, it is affection rather than strength which keeps the members of a group together. Although among most of the lower orders the female exercises a choice in the selection of her mate, still among animals of polygamous habits the female is said to manifest genuine affection for the father of her offspring.
The polygamic regime of animals is far from extinguishing affectionate sentiments in the females towards their husband and master. The females of the guanaco lamas, for example, are very faithful to their male. If the latter happens to be wounded or killed, instead of running away, they hasten to his side, bleating and offering themselves to the shots of the hunter in order to shield him, while, on the contrary, if a female is killed, the male makes off with all his troop; he only thinks of himself.[60]
Although among animals a stray male will sometimes drive away or kill all the other males of the group, and himself become the common mate of all the females, they peaceably accepting the situation, so far as I can find, female insects, birds, and mammals, although they generally control the sexual relation, have never been given to polyandry; the reason for this can be explained only through a careful analysis of the fundamental bias of the female constitution. We must bear in mind that although among the orders of life below mankind the male is ready to pair with any female, she, on the other hand, when free to choose, can be induced to accept the attentions only of the one which by his courage, bravery, or personal beauty has won her favours. We have noted the fact that in the earliest ages of the human race this choice was exercised by women, but we have no reason to believe that anything resembling “promiscuity” ever prevailed among primitive races. It is true that under earlier conditions the institution of marriage as it exists at the present time had not appeared; yet the law which had been impressed on the higher organism of the female, until overcome by males through means which will be treated of later in these pages, had sufficed to keep the animal instincts under subjection, or at least on a level with those of the lower species which structurally had been left behind.
From facts to be gathered, not alone from among the lower orders, but from observations among human beings as well, it would seem that any degree of affection for more than one individual at the same time is contrary to the female nature. A female insect, or bird, which feels a preference for a particular mate will pair with no other, hence, among orders where the female instincts control the relations between the sexes, “lawlessness” or promiscuity would not prevail.
A little observation and reflection, I think, will show us that the affection of the female is a character differing widely from the sex instinct of the male—that, while selfishness constitutes the underlying principle of the latter, the former involves not only care for the young and the unity of the group, but, when human conditions are reached, it involves also country, civilization, and the ultimate brotherhood of mankind.
If we bear in mind the conditions surrounding the orders of life from which the human race has sprung, and if we remember the nature of the characters inherited by mankind from these orders, together with the important fact that the lower instincts among them were under subjection to the higher faculties, we shall be enabled to see that the more degraded of the extant savage tribes cannot represent the primitive race as it emerged from the animal type.
Mr. Tylor must have been mindful of the altruistic character of early races when he remarked: “Without some control beyond the mere right of the stronger, the tribe would break up in a week, whereas in fact savage tribes last on for ages.”[61]
Concerning the relations of the sexes under unorganized society nothing may be known from actual observation, as, at the present time, no tribe or race is to be found under absolutely primitive conditions. Perhaps from no extant people is there so little information in reference to the earliest human state to be gleaned as from the lowest existing races. Among many of these tribes the rules which it has been necessary to establish for the regulation of the relations between the sexes are rigorously enforced, while among others a laxity prevails which would seem to indicate an almost total lack of those higher instincts which are observed among nearly all the lower orders of beings. The following fact, however, in regard to these races, has been observed: the more primitive they are, or the less they have come in contact with civilization, the more strictly do they observe the rules which have been established for the governance of the sexual relation. On this subject Mr. Parkyns says:
